I notice the endpoints.json file doesn't include a reference to wellarchitected. Not sure if related.

Hi @benfortuna, you'll need boto3>=11.16.38 (botocore>=.19.38) to use this service. If you are running an older version, you'll need to upgrade. For your future reference, you can see when this was added in the API model, not the endpoint file:

@kdaily I have tried with latest boto3/botocore. If I have requirements.txt as

boto3>=1.16.38
botocore>=1.19.38

I get the same error as described above. Pls dont close ticket prematurely.

FYI resolved issue. Looks like an older Python 3.6 install was being executed, which doesn't appear to support wellarchitected client.
